Problems solved by technology

Due to the lack of sufficient theoretical and method support, the aforementioned methods often have problems such as a large number of sub-models obtained by splitting, high modeling pressure, and loss of color gamut.
For the above problems, neither academia nor industry has proposed an efficient and reasonable split modeling method for printing and printing systems from the perspective of maximizing the color gamut.

Embodiment Construction

[0036] When the technical solution of the present invention is specifically implemented, it can be run by those skilled in the art using computer software technology. In conjunction with the accompanying drawings, the specific description of the embodiments of the present invention is provided as follows.

[0037] Such as figure 1 As shown, the embodiment provides a multi-color printing printing system split modeling method for maximizing the color gamut, which can be used while improving modeling efficiency, avoiding ink overrun, and improving overprint color stability. The printing output effect of maximizing the color gamut. The embodiment adopts a CMYKRGB seven-color inkjet printer, wherein CMYKRGB is cyan (Cyan), magenta or magenta (Magenta), yellow (Yellow), black (Black), red (Red), green (Green) and blue ( Blue) shorthand for seven colors. It should be noted that the present invention is not limited to the application of split modeling of seven-color printers, and t...

Abstract

A multicolor printing system splitting modeling method for maximizing a color gamut comprises steps of manufacturing and printing single color step-wedges of all primary colors, determining the ultralimit threshold value of each single color ink quantity, measuring the spectrum value of each single-color step-wedge subjected to equal ratio compression and establishing a corresponding relation; splitting an original multicolor printing system into printing system submodels; performing ink color space overall sampling to obtain the sampling samples under the sprinting system submodels, and obtaining the prediction spectrum reflectivity information values by simulation; targeting at all submodels, using a convex hull algorithm to calculate to obtain the ink color space overall sampling color gamut volumes; combining K submodels and using the convex hull algorithm to obtain the color gamut volume of each combination, and locking the combination corresponding to the maximum color gamut coverage rate when the maximum color gamut coverage rate is larger than the preset threshold value, thus realizing the splitting modeling of the original printing system. The method has the technical advantages of obviously reducing the splitting modeling complexity of the system, avoiding the ink quantity ultralimit problem, improving the stability of output colors and the like.

Description

technical field [0001] The invention belongs to the technical field of multi-color printing and printing color reproduction, and in particular relates to a multi-color printing and printing system split modeling method for maximizing the color gamut. Background technique [0002] Multi-color printing Printing color reproduction technology is one of the mainstream technologies in the field of image reproduction at home and abroad. This technology uses the image color control value input by the user as the original data, and realizes the color reproduction process of the image according to the correlation model between the input and output volumes established in advance. Compared with traditional printing and printing color reproduction methods, multi-color printing and printing color reproduction technology has technical advantages such as a wide range of color reproduction color gamut, rich color levels of reproductions, and clear details. [0003] In the process of impleme...
